Hundreds of farmers, producers and exporters have lined the foreshore under Fremantle's Stirling Bridge in Western Australia as part of a counter rally against a live exports protest.

The agricultural industry claims their sector has been unfairly represented in the live export debate and claim their industry upholds and promotes animal welfare.

Export rally organiser Michael Trant says the agricultural industry has been unfairly represented, ever since vision showing the inhumane slaughter of Australian sheep in Pakistan was aired on the ABC's Four Corners program earlier this year.

Mr Trant says stopping the live trade would force international buyers to look elsewhere.

"What happened with Pakistan was an unforeseen isolated, couldn't even been imagined incident," he said.

"It's just a foreign government comes in and hijacks sheep.

"It's just unheard of."

Animal activists lined the bridge above the industry representatives, dressed in black to form what they have described as a human chain.
